Abstract

PURPOSE: To make a structure light and compact as a whole by making a rotary bearing device itself smaller in diameter and its outer and inner wheels thinner in thickness in the structure used for a power shovel and the like.
CONSTITUTION: Between a base stock 1 and a rotary body 2 applying vertical and moment loads to the base stock 1 is provided a rotary bearing device 3 holding many rolling bodies 13 between inner and outer wheels 11 and 12, thereby the rotary body 2 being supported so that it is rotated against the base stock 1. In the supporting structure for the rotary body thus constituted, one of the inner and outer wheels 11 and 12 of the rotary bearing device 3 and the base stock 1, as well as the other one of the wheels and the rotary body 2, are put in one body on the whole periphery through solid forming or welding, without using any rodlike connecting membter such as a bolt.
